Abstract
The phase of digitally synthesized audio frequency signals of the same frequency is synchronized prior to conversion of the signals into analog form. The phase synchronization is accomplished, in a musical instrument of the keyboard type, by comparison of the digitally coded signals which are commensurate with all of the simultaneously generated input commands and, when frequency coincidence is detected, employing the phase value of the first of plural commanded signal at the same frequency as the starring phase value for subsequently generated signals at the common frequency.
